Penguin Planter/Pencil Holder RARE Antique

I have always used this as a pencil/pen holder in my kitchen. I received it as a gift in 1963 and it was an antique then. It does have a stamp on the bottom but I cannot remember the history. There is a small chip on one of the right toes. 6.5" Tall- 4.7" wide I've never seen another like it. Questions Welcomed - Smoke Free FAST SHIPPING!
